[1. Embodiment)
[1-1. Presentation processing according to embodiment]
First, an example of presentation processing according to the embodiment will be described with reference to FIG. Drawing 1 is an explanatory view showing an example of presentation processing by presentation system 1 concerning an embodiment. In the presentation system 1, as shown in FIG. 1, the information processing apparatus 100 gives a summary of technical terms included in a lecture of a speaker SM (corresponding to an example of a speaker) to audiences U1 to U2 (corresponding to an example of a listener). The presentation process to present is performed.

  As shown in FIG. 1, the presentation system 1 includes a speaker terminal 10, audience terminals 20 </ b> A to 20 </ b> B, an information providing apparatus 50, and an information processing apparatus 100. The speaker terminal 10, the audience terminals 20A to 20B, the information providing apparatus 50, and the information processing apparatus 100 are communicably connected to the network by wireless or wired communication. Hereinafter, when the devices of the audience terminals 20A to 20B are collectively referred to without distinction, they may be referred to as “audience terminal 20”.

  The speaker terminal 10 is an information processing apparatus such as a smartphone, a tablet terminal, a mobile phone, a PC (Personal Computer), or a PDA (Personal Digital Assistant). Specifically, the speaker terminal 10 is owned by the speaker SM who is the speaker of the lecture. For example, the speaker terminal 10 has a function of recording sound emitted from a speaker and a function of recognizing sound.

  The audience terminal 20 is an information processing apparatus such as a smartphone, a tablet terminal, a mobile phone, a PC, or a PDA. Specifically, the audience terminal 20 is owned by the audience U1 to U2 who are listeners of the lecture. For example, the audience terminal 20 has a function of displaying a summary of technical terms on a screen.

  The information providing device 50 is a server device that provides various types of information. Specifically, the information providing apparatus 50 provides the meaning of a term as an Internet encyclopedia. For example, when the information providing apparatus 50 receives a search query, the information providing apparatus 50 provides commentary information on terms corresponding to the search query to the transmission source apparatus.

  The information processing apparatus 100 is a server apparatus that outputs a summary of technical terms. Specifically, the information processing apparatus 100 first receives information related to sound (step S1). More specifically, the information processing apparatus 100 receives from the speaker terminal 10 a speech recognition result SR1 “pending because indirect finance was Nash balanced” as a speech-related information from a part of the lecture of the speaker SM. Receive.

  Subsequently, the information processing apparatus 100 extracts terms included in the received information related to the voice (step S2). Specifically, the information processing apparatus 100 extracts the terms “indirect finance”, “Nash equilibrium”, and “pending” included in the received speech recognition result SR1 (step S2).

  Then, the information processing apparatus 100 generates a summary of the extracted terms (step S3). Specifically, the information processing apparatus 100 uses the information providing apparatus 50 to generate summaries of “indirect finance”, “Nash equilibrium”, and “pending”, respectively. As an example, the information processing apparatus 100 transmits “indirect finance” to the information providing apparatus 50 as a search query. Subsequently, the information processing apparatus 100 receives “indirect finance” commentary information from the information providing apparatus 50 as a response to the search query. Then, the information processing apparatus 100 refers to the received commentary information on “indirect finance” and summarizes Ab1 “indirect finance”, which indirectly lends and borrows funds between the lender and the recipient. It is a mechanism that an institution exists. Similarly, the information processing apparatus 100 generates the summary Nb2 “Nash equilibrium”, “A kind of solution of the non-cooperative game in game theory, and the most basic concept among several solutions”. To do. Further, the information processing apparatus 100 is a foreign word meaning “abnormal”, “pending”, or “deferred” summary Ab3 of “pending”, but the nuance may differ slightly depending on the industry. Is generated.

  Subsequently, in the information processing apparatus 100, the audience U1 has a summary of technical terms corresponding to the audience U1 among “indirect finance”, “Nash equilibrium”, and “pending” extracted as terms included in the information related to speech. Output to the audience terminal 20A in real time (step S4). Here, it is assumed that the audience U1 is an expert of “music”. In other words, the audience U1 has “music” as the user attribute. In this case, the information processing apparatus 100 uses the abstracts Ab1 to Ab3 of “indirect finance”, “Nash equilibrium”, and “pending” that are terms belonging to fields other than “music” as technical terms corresponding to the audience U1. Is output to the audience terminal 20A. As a result, the audience terminal 20A displays the sums Ab1 to Ab3 of “indirect finance”, “Nash equilibrium”, and “pending” on the screen in real time as shown in FIG.

  In addition, the information processing apparatus 100 has an audience that the audience U2 has a summary of technical terms corresponding to the audience U2 among “indirect finance”, “Nash equilibrium”, and “pending” extracted as terms included in the information related to audio. Output to the terminal 20B in real time (step S5). Here, it is assumed that the audience U2 is an expert of “finance” and “economy”. In other words, the audience U2 has “finance” and “economy” as user attributes. In this case, the information processing apparatus 100 outputs a summary of “pending”, which is a term belonging to a field other than “finance” and “economy”, as technical terms corresponding to the audience U2, to the audience terminal 20B. On the other hand, the information processing apparatus 100 does not output the summary of “indirect finance” and “Nash equilibrium”, which are terms belonging to the fields of “finance” and “economy”, to the audience terminal 20B. Thereby, as shown in FIG. 1, the audience terminal 20B does not display the sums Ab1 to Ab2 of “indirect finance” and “Nash equilibrium”, but displays the summary Ab3 of “pending” on the screen in real time.

  As described above, the information processing apparatus 100 according to the embodiment receives information related to sound. In addition, the information processing apparatus 100 extracts terms included in the received information related to speech. In addition, the information processing apparatus 100 outputs a summary of technical terms corresponding to the listener among the extracted terms.

  Thus, the information processing apparatus 100 can output technical terms corresponding to the listener among the terms included in the voice of the speaker, and can display an explanation of the term appropriate for the listener. For example, the information processing apparatus 100 can output a summary of terms that belong to a field that the listener does not specialize, and therefore can display a summary of terms that the user wants to know. Further, since the information processing apparatus 100 does not output a summary of terms belonging to the field that the listener specializes in, it is possible to prevent the display of terms that do not require explanation for the user and to keep the visibility high.

  Although FIG. 1 shows an example in which the presentation system 1 includes one speaker terminal 10, two audience terminals 20A to 20B, and one information processing apparatus 100, the presentation system 1 May include a plurality of speaker terminals 10, a plurality of audience terminals 20 </ b> A to 20 </ b> B, and a plurality of information processing apparatuses 100.

  In addition, in FIG. 1, for the sake of simplicity, an example of “pending because indirect finance was Nash equilibrium”, which is a part of the lecture of the lecturer SM, is shown as an example. A summary of technical terms is displayed sequentially in real time whenever technical terms included in the lecture appear.

For example, the extraction unit 132 extracts nouns from words included in the speech recognition result. As an example, the extraction unit 132 extracts a term included in the speech recognition result by collating the Roman character reading of the combination of nouns included in the speech recognition result with the Roman character reading of the article name published in the Internet encyclopedia or the like. To do. Thereby, the extraction part 132 can prevent the extraction of a term from failing by notation fluctuations (for example, numbers and Chinese numerals). Then, the extraction unit 132 stores the extracted terms in the term information storage unit 122. For example, the extraction unit 132 assigns an individual term ID to the extracted term, and stores the term in the term information storage unit 122 in association with the voice ID and the term ID.

(About the generator 133)
The generation unit 133 generates a summary of terms extracted by the extraction unit 132. Specifically, the generation unit 133 uses the information providing device 50 to generate a summary of terms included in information related to speech. For example, the generation unit 133 first transmits the term extracted by the extraction unit 132 to the information providing apparatus 50 as a search query. Subsequently, the generation unit 133 receives, from the information providing apparatus 50, terminology explanation information (for example, an article of a search result obtained by searching a search query in Wikipedia (registered trademark)) as a response to the transmitted search query. Then, the information processing apparatus 100 generates a summary of terms using the received explanation information of terms.

  This point will be described in detail with reference to FIG. FIG. 6 is an explanatory diagram for explaining a generation process for generating a summary of terms. In the example of FIG. 6, the generation unit 133 generates a summary Ab2 of the term “Nash equilibrium”. Specifically, as shown in FIG. 6, the generation unit 133 uses the first paragraph Pr1 among the explanation information Cm formed by the first paragraph Pr1, the second paragraph Pr2, and the third paragraph Pr3, and uses the term “Nash”. A balance Ab2 summary Ab2 is generated. More specifically, the generation unit 133 first extracts the first paragraph Pr1 from the comment information Cm. Subsequently, the generation unit 133 deletes redundant expressions from the first paragraph Pr1 of the extracted commentary information Cm. For example, the generation unit 133 deletes a portion corresponding to “to” from the first sentence of the first paragraph Pr1 of the comment information Cm. In the example of FIG. 6, “˜” means “Nash equilibrium” which is a term for which a summary is generated. In addition, the generation unit 133 deletes a portion corresponding to “˜” from the entire first paragraph Pr1 of the comment information Cm. Then, the generation unit 133 adjusts the overall length of the remaining sentence of the first paragraph Pr1 within a predetermined range. For example, when the length of the remaining sentence of the first paragraph is longer than the predetermined range, the generation unit 133 deletes a part of the remaining sentence of the first paragraph so as to be within the predetermined range. Accordingly, the generation unit 133 generates a summary Ab2 of “Nash equilibrium”. On the other hand, when the length of the remaining sentence of the first paragraph is shorter than the predetermined range, the generating unit 133 combines, for example, the remaining sentence of the first paragraph and the deleted sentence of the first paragraph. Generate a summary. In another example, the generation unit 133 performs the same process as the first paragraph using the contents of the second paragraph, and generates a summary combining the remaining sentences of the first paragraph and the remaining sentences of the second paragraph. To do. Then, the generation unit 133 stores the generated term summary in the term information storage unit 122. For example, the generation unit 133 stores the generated term summary in the term information storage unit 122 in association with the term ID.

(About the output unit 134)
The output unit 134 outputs a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132. Specifically, the output unit 134 outputs a summary of technical terms corresponding to the listener based on the field to which the term extracted by the extraction unit 132 belongs. . For example, the output unit 134 outputs a summary of technical terms based on the user attributes of the listener. As an example, the output unit 134 refers to the user information storage unit 123, and among the summary of terms generated by the generation unit 133, the audience that the user has a summary of terms belonging to a field other than the user attribute of the user. Output to the terminal 20 in real time.

  In another example, the output unit 134 outputs a summary of technical terms whose terminology degree based on the appearance frequency is greater than or equal to a predetermined threshold among terms included in information related to speech. For example, the output unit 134 outputs a summary of terms whose IDF (Inverse Document Frequency) value represented by the following formula (1) is a predetermined threshold or more as the technical term degree.

Here, “N” in the formula (1) indicates the total number of articles in the Internet encyclopedia. In addition, “df _j ” in Expression (1) indicates the frequency at which the article name appears in the document. Therefore, the output unit 134 determines that a term having a lower appearance frequency is a specialized term and outputs the summary with priority. As an example, the IDF value is calculated by distributed processing using Hadoop.

  Here, the output unit 134 may output a summary of technical terms based on a threshold value of technical terms adjusted according to user attributes. For example, the output unit 134 outputs a summary of terms having a technical term degree equal to or greater than a threshold adjusted by changing the weight of a coefficient of a calculation formula for calculating the technical term degree according to the user attribute.

[1-3. Presentation processing procedure according to embodiment]
Next, the procedure of processing by the presentation system 1 according to the embodiment will be described with reference to FIG. FIG. 7 is a sequence showing a presentation processing procedure by the presentation system 1 according to the embodiment.

  As illustrated in FIG. 7, the information processing apparatus 100 receives information related to speech from the speaker terminal 10 (step S <b> 101). For example, the information processing apparatus 100 receives from the speaker terminal 10 a speech recognition result obtained by recognizing speech generated by a speaker as information related to speech. When the information processing apparatus 100 receives information related to sound, the information processing apparatus 100 stores the received information related to sound in the sound information storage unit 121.

  Subsequently, the information processing apparatus 100 extracts terms included in the received information related to the voice (step S102). For example, the information processing apparatus 100 extracts terms included in the speech recognition result received from the speaker terminal 10 as information related to speech. Then, the information processing apparatus 100 stores the extracted terms in the term information storage unit 122.

  Thereafter, the information processing apparatus 100 transmits the extracted term as a search query to the information providing apparatus 50 (step S103). Then, the information processing apparatus 100 receives commentary information on terms from the information providing apparatus 50 as a response to the transmitted search query (step S104). Subsequently, the information processing apparatus 100 generates a summary of terms based on the received explanation information of terms (step S105). Then, the information processing apparatus 100 stores the generated summary in the term information storage unit 122 in association with the term.

  Subsequently, the information processing apparatus 100 outputs a summary of technical terms corresponding to the listener among the extracted terms (step S106). For example, the information processing apparatus 100 refers to the user information storage unit 123 and outputs a summary of terms belonging to a field other than the user attribute possessed by the user to the audience terminal 20 possessed by the user. .

[1-4. Effects of the embodiment
As described above, the information processing apparatus 100 according to the embodiment includes the reception unit 131, the extraction unit 132, and the output unit 134. The receiving unit 131 receives information related to audio. The extraction unit 132 extracts terms included in the information regarding the sound received by the reception unit 131. The output unit 134 outputs a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132.

  Thus, the information processing apparatus 100 can output technical terms corresponding to the listener among the terms included in the voice of the speaker, and can display an explanation of the term appropriate for the listener. For example, the information processing apparatus 100 can output a summary of terms that belong to a field that the listener does not specialize, and therefore can display a summary of terms that the user wants to know. Further, since the information processing apparatus 100 does not output a summary of terms belonging to the field that the listener specializes in, it is possible to prevent the display of terms that do not require explanation for the user and to keep the visibility high.

  In the information processing apparatus 100 according to the embodiment, the output unit 134 outputs a summary of technical terms corresponding to the listener based on the field to which the term extracted by the extraction unit 132 belongs. As a result, the information processing apparatus 100 can present to the listener a summary of terms belonging to a field that is not familiar to the listener, and thus can support the listener's audition. For example, since the information processing apparatus 100 can automatically present a summary of terms according to the listener, it is possible to reduce the effort for the listener to actively search for technical terms.

  Further, in the information processing apparatus 100 according to the embodiment, the output unit 134 outputs a summary of technical terms whose terminology degree based on the appearance frequency is greater than or equal to a predetermined threshold among terms included in the information related to speech. As a result, the information processing apparatus 100 can output a summary of technical terms with a low appearance frequency, and thus can present a summary of terms that are highly likely to be unknown to the listener. For example, the information processing apparatus 100 does not output a summary of terms having a high application frequency, so that it is possible to prevent a summary of terms familiar to the user from being displayed and maintain high visibility.

  In the information processing apparatus 100 according to the embodiment, the output unit 134 outputs a summary of technical terms based on the user attributes of the listener. As a result, the information processing apparatus 100 can output a summary of terms belonging to a field that is not familiar to the listener, and thus can present a summary of terms that the listener is likely not to know. For example, since the information processing apparatus 100 can output a summary of terms belonging to a field other than the listener's specialty, it can support the listener's audition.

[2. (Modification)
The information processing apparatus 100 according to the above-described embodiment may be implemented in various different forms other than the above-described embodiment. Therefore, hereinafter, another embodiment of the information processing apparatus 100 will be described.

[2-1. (Summary according to the operation of the listener)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may output a summary of technical terms corresponding to the operation of the listener.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs a summary of technical terms based on an operation related to the summary of technical terms by a listener. In other words, the output unit 134 feeds back the audience's operation on the technical term summary and outputs the technical term summary. For example, the output unit 134 outputs a summary of technical terms based on a listener selection operation or deletion operation on the technical term summary.

  This point will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of a display screen. As shown in FIG. 8, the audience terminal 20 displays a link button Li corresponding to the term together with the term summary Ab. Here, the audience terminal 20 transitions to an article of the Internet encyclopedia corresponding to the term when the link button Li is selected by the listener. Then, for example, the information processing apparatus 100 preferentially outputs the summary Ab when the term appears in the future, assuming that the term is more specialized as the number of selection operations for selecting the link button Li corresponding to the term increases. To do.

  The information processing apparatus 100 may output a summary of technical terms based on the number of various selection operations without being limited to the number of selection operations for selecting the link button Li. For example, the information processing apparatus 100 assumes that the more the number of selection operations for selecting a “useful” button (not shown) displayed corresponding to the summary of the term, the more specialized the term is, and the term appears in the future. A summary of such terms may be output with priority.

  In another example, the audience terminal 20 deletes the summary Ab from the display screen when a flick operation is performed in which the finger is quickly moved left and right on the summary Ab displayed on the screen. The information processing apparatus 100, for example, assumes that the term is not a technical term as the number of deletion operations for deleting the term summary Ab from the screen is large. Do not output with priority.

  Note that the information processing apparatus 100 may output a summary of technical terms based on the number of deletion operations performed by various operations, not limited to a deletion operation by a flick operation on a summary. For example, the information processing apparatus 100 takes a case where such a term appears in the future, assuming that the term is not a technical term as the number of selection operations for selecting a “delete” button (not shown) displayed corresponding to the term summary is larger. The summary of terms may not be output with priority.

  As described above, the information processing apparatus 100 according to the modification outputs a summary of technical terms based on an operation related to the summary of technical terms by a listener. As a result, the information processing apparatus 100 can output a summary of terms according to the listener's reaction to the summary, and can display a description of terms appropriate for the listener.

  In addition, the information processing apparatus 100 according to the modification outputs a summary of technical terms based on a listener's selection operation or deletion operation on the technical term summary. As a result, the information processing apparatus 100 can output a summary of terms that the listener tends to investigate deeply, and can display explanations of terms that the listener is likely to know. Further, since the information processing apparatus 100 can output a summary of terms that the listener tends to delete, explanations of common-sense terms that do not need to be displayed for the listener are displayed and are easy to see. Can be prevented from being damaged.

[2-2. (The listener's operation status is output to the speaker.)
In the above modification, the information processing apparatus 100 has been described by taking an example in which a summary of terms is output according to a listener's reaction to the summary. Here, the information processing apparatus 100 may output the operation state of the listener for the summary to the speaker.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs the operation status related to the summary of the technical terms by the listener to the speaker of the information related to speech. For example, the information processing apparatus 100 outputs, in real time, the number of times the selection operation has been performed on the summary of terms as the operation status related to the summary in association with the term. In another example, the information processing apparatus 100 outputs, to the speaker terminal 10 in real time, the number of deletions performed on the summary of terms as the operation status related to the summary in association with the term.

  As described above, the information processing apparatus 100 according to the modified example outputs the operation status related to the summary of the technical terms by the listener to the speaker of the information related to the voice. As a result, the information processing apparatus 100 can notify the speaker of operations performed by the listener on the summary, thereby improving the quality of the speaker's lecture. For example, the information processing apparatus 100 can notify the speaker of the number of times that the selection operation has been performed on the term summary, and thus allows the speaker to grasp a term that the listener does not understand. Further, since the information processing apparatus 100 can notify the speaker of the number of times the deletion operation has been performed on the term summary, the speaker can grasp the term understood by the listener. For this reason, since the information processing apparatus 100 can measure the effect by an operation on the summary of terms, it is possible to provide information useful for the speaker to grasp the understanding level of the listener.

[2-3. (Output at the timing according to the listener)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may output the summary at a timing according to the listener.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs a summary of technical terms with a higher frequency as the knowledge of the field in the information regarding the listener's voice is shallower. For example, the output unit 134 outputs the technical term summary with a higher frequency as the number of times the listener refers to the technical term summary increases. As an example, the information processing apparatus 100 outputs the term summary to the audience terminal 20 as the number of times that the listener selects the term summary and changes to the article corresponding to the term increases. In other words, the information processing apparatus 100 outputs a summary of terms each time a technical term appears when the number of listeners selected is greater than a predetermined number and the knowledge level is basic. On the other hand, the information processing apparatus 100 outputs a summary of terms collectively at the end of a story when the number of selections by the listener is less than a predetermined number and the knowledge level is intermediate or higher.

  As described above, the information processing apparatus 100 according to the modified example outputs a summary of technical terms with higher frequency as the knowledge of the field in the information related to the voice of the listener is shallower. As a result, the information processing apparatus 100 can output a summary according to the knowledge of the listener, so that the summary can be displayed at a timing suitable for the listener. For example, when the listener is a beginner, the information processing apparatus 100 can present a summary as soon as a technical term appears. On the other hand, the information processing apparatus 100 can prevent the annoyance that term summaries frequently appear when the listener is intermediate or higher.

  Further, the information processing apparatus 100 according to the modified example outputs the technical term summary more frequently as the number of times the listener refers to the technical term summary increases. Thereby, since the information processing apparatus 100 can estimate the level of the listener with high accuracy, the summary can be presented at a timing suitable for the listener.

[2-4. (Term ranking)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may output information on terms in various forms.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs a term ranking in which technical terms are arranged in descending order of the number of listeners selected with respect to the summary of technical terms or in the order of few deletions. For example, the information processing apparatus 100 outputs to the audience terminal 20 a table in which the number of selections for the summary is associated with the term name and arranged in ascending order. In another example, the information processing apparatus 100 outputs to the audience terminal 20 a table in which the number of deletions for the summary is associated with the term name and arranged in descending order.

  As described above, the information processing apparatus 100 according to the modified example outputs a term ranking in which technical terms are arranged in descending order of the number of listeners selected with respect to the summary of technical terms or in the order of few deletions. As a result, the information processing apparatus 100 can provide information that allows a user to easily grasp a term that the listener does not know compared to other terms, thereby improving the convenience of the listener.

[2-5. grouping〕
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may output information on technical terms in various forms.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs technical terms corresponding to the listener among the terms extracted by the extracting unit 132 for each group to which the technical terms belong. For example, the information processing apparatus 100 outputs a table in which technical terms are classified by field to the audience terminal 20. In another example, the information processing apparatus 100 outputs, to the audience terminal 20, a table in which technical terms are grouped and classified for each time zone that appears in the lecture. As an example, the information processing apparatus 100 outputs to the audience terminal 20 a table in which technical terms appearing at the question and answer time of the lecture are collected.

  As described above, the information processing apparatus 100 according to the modification outputs the technical terms corresponding to the listener among the terms extracted by the extraction unit 132 for each group to which the technical terms belong. Thereby, since the information processing apparatus 100 can make it understand the tendency of a technical term, it can provide useful information for a speaker or a listener.

[2-6. Correct the amount of summarization)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may correct the amount of summary based on various types of information.

  Specifically, the output unit 134 of the information processing apparatus 100 corrects and outputs the technical term summary amount based on an operation related to the technical term summary by the listener. In other words, the information processing apparatus 100 corrects the number of characters in the summary by feeding back the listener's operation on the summary. For example, the information processing apparatus 100 increases the number of characters in the summary and outputs the result to the audience terminal 20 as the technical term is more specialized as the number of selection operations for selecting a link button that transitions to a term article increases. On the other hand, the information processing apparatus 100 reduces the number of characters in the summary and outputs the result to the audience terminal 20 as the number of deletion operations for deleting the summary of the term increases as the term is not a specialized term.

  As described above, the information processing apparatus 100 according to the modified example corrects and outputs the technical term summary amount based on the operation related to the technical term summary by the listener. Thus, the information processing apparatus 100 can output a summary reflecting the operation result for the summary, and thus can provide a high-quality summary for the listener.

[2-7. (Defining technical terms)
In the above-described embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms whose terminology degree based on the appearance frequency is greater than or equal to a predetermined threshold among terms included in the information related to speech is output. Here, the information processing apparatus 100 may output a summary of technical terms based on a technical term degree threshold set by the listener.

  This point will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of the setting screen. For example, when the audience terminal 20 receives an operation for transition from the listener to the setting screen, as shown in FIG. 9, the threshold value of the technical term is set by moving the knob Bu left and right on the setting bar Br. Display the setting screen. As an example, the threshold value of the technical term level is set to a lower value as the knob Bu is located on the left of the setting bar Br. On the other hand, the threshold value of the technical term is set higher as the knob Bu is positioned on the right of the setting bar Br.

  Then, the information processing apparatus 100 outputs a summary of technical terms to the audience terminal 20 based on a threshold value of technical terms set by the position of the knob Bu on the setting bar Br. In other words, the information processing apparatus 100 adjusts the summary of technical terms to be output based on the technical term degree threshold set by the listener. Specifically, the information processing device 100 outputs a summary of many technical terms to the audience device 20 because the threshold of the technical term level is set lower as the knob Bu is located on the left of the setting bar Br. . On the other hand, the information processing apparatus 100 outputs a summary of technical terms to the audience device 20 because the threshold value of the technical term level is set higher as the knob Bu is positioned to the right of the setting bar Br.

  As described above, the information processing apparatus 100 according to the modification outputs a summary of technical terms based on the technical term degree threshold set by the listener. As a result, the information processing apparatus 100 can output a summary of technical terms that are higher than the level desired by the listener, so that satisfaction of the listener can be increased.

[2-8. (Select a lecture)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may output a summary of technical terms included in the lecture lecture selected by the listener.

  This point will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of the selection screen. For example, as shown in FIG. 10, the audience terminal 20 provides a lecture Rm1 “quartet first lecture”, a lecture Rm2 “quartet second seminar”, and a lecture Rm3 “quartet third meeting” that can output a summary of technical terms. Display the list of posted seminars on the screen. Here, the audience terminal 20 accepts the lecture selected by the listener from the lectures Rm1 to Rm3. Then, the information processing apparatus 100 outputs to the audience terminal 20 a summary of technical terms corresponding to the listener among the terms included in the lecture lecture selected by the listener.

  In this way, the information processing apparatus 100 according to the modification outputs a summary of technical terms included in the lecture lecture selected by the listener. Accordingly, the information processing apparatus 100 can output a summary of technical terms in a lecture desired by the listener, and therefore provides a summary of technical terms desired by the listener even when a plurality of lectures are performed simultaneously. Can do.

[2-9. (Personalize)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms is output based on the user attribute of the listener. Here, the information processing apparatus 100 may output a summary of technical terms corresponding to the listener based on various types of information.

  Specifically, the information processing apparatus 100 outputs a summary of technical terms based on the similarity with other listeners. For example, the information processing apparatus 100 outputs a summary of technical terms based on a selection operation performed on the summary by another listener who has a similar usage history in another service or the like. As an example, the information processing apparatus 100 preferentially outputs a summary of a term that has been subjected to many selection operations on the summary by other similar listeners.

  In another example, the information processing apparatus 100 outputs a summary of technical terms based on a history of technical term summaries output to the listener in the past. For example, when a term appears that has been output to the audience terminal 20 once in the past, the information processing apparatus 100 does not output the summary of the term to the same audience terminal 20. In other words, the information processing apparatus 100 does not output the same term summary for the same listener.

  Thus, the information processing apparatus 100 according to the modification outputs a summary of technical terms corresponding to the listener based on various types of information. As a result, the information processing apparatus 100 can provide a summary of terms specific to the listener, thereby improving convenience for the listener.

[2-10. (Applicable)
In the above embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms included in the lecturer's lecture is output to the audience. Here, the information processing apparatus 100 may apply not only a lecture but also various utterances. Specifically, the information processing apparatus 100 outputs a summary of technical terms included in a conversation between a speaker and a listener having different knowledge levels. For example, the information processing apparatus 100 outputs a summary of technical terms included in a class conducted by a teacher for a student. In another example, the information processing apparatus 100 outputs a summary of technical terms included in a diagnosis performed by a doctor on a patient.

  The information processing apparatus 100 may apply language learning as an application. For example, the information processing apparatus 100 first receives a speech recognition result obtained by recognizing speech made in English from the speaker terminal 10. Subsequently, the information processing apparatus 100 translates the received speech recognition result from English to Japanese. Then, the information processing apparatus 100 transmits the speech recognition result translated into Japanese to the audience terminal 20 of the Japanese audience.

  Further, in the above-described embodiment, the information processing apparatus 100 has been described with an example in which a summary of technical terms is output to a smartphone. Here, the information processing apparatus 100 may output a summary of technical terms to various terminal devices such as a tablet terminal and a PC, not limited to a smartphone.

Thereby, the information processing apparatus 100 can provide the listener with a summary of technical terms and Japanese translations included in various utterances as well as lectures.

[2-11. A summary of terminology is output based on the knowledge difference between the speaker and the listener)
In the above embodiment, an example has been described in which a summary of technical terms corresponding to the listener among the terms extracted by the extraction unit 132 is output. Here, the information processing apparatus 100 may employ a knowledge difference between the speaker and the listener as a determination criterion.

  Specifically, the output unit 134 of the information processing apparatus 100 outputs a summary of technical terms based on a knowledge difference between a speaker and a listener of information related to speech. For example, the information processing apparatus 100 sets the knowledge level of the listener and the speaker in the lecture theme and field spoken by the speaker. As one aspect, the level accepted from a speaker or listener may be set as the knowledge level, or may be set based on an action history or a profile. The information processing apparatus 100 then outputs a summary of technical terms based on the difference between the knowledge levels of the listener and the speaker. As an example, the information processing apparatus 100 outputs a relatively large number of technical term summaries by setting a predetermined threshold value of the technical term level lower as the knowledge level difference is higher.

  In another example, the information processing apparatus 100 outputs a summary of technical terms based on the user attributes of the speaker and the user attributes of the listener. As an example, when the user attribute of the speaker is different from the user attribute of the listener, the information processing apparatus 100 adjusts a predetermined threshold of technical terms and outputs a technical term summary. As one aspect, the information processing apparatus 100 sets the predetermined terminology degree threshold value lower as the similarity between the user attribute of the speaker and the user attribute of the listener is lower. Output a lot.

  As described above, the information processing apparatus 100 according to the modification outputs a summary of technical terms based on a knowledge difference between a speaker and a listener of information related to speech. Thus, the information processing apparatus 100 can output a summary of technical terms in consideration of the knowledge difference between the speaker and the listener, and thus can support the listener's listening. For example, the information processing apparatus 100 can output more summaries as the subject area of the speaker is different from the subject area of the listener, so that it is possible to prevent the listener from being unable to follow the story due to insufficient understanding of terms.
